LOCOMOTIVE-TENDER.

Be it known that 1, JOHN E. MUHLFELD, of Scarsdale, in the county of lVestchester and State of New York,have invented a certain new and useful Improvement in Locomotive-Tenders, ofwhich improvement the My invention more particularly relates to tenders for locomotives which burn pulverized fuel, and its object is to provide means for the'storage of fuel of such character and of water, by which condensation (in, or sweating of, the fuel receptacle, and-result ant interference with the free flow of fuel are prevented; obstruction of said receptacle by pockets or projections avoided and facilities afforded for the conveyance of fuel 1 to desired points of delivery. on the locomotive, without liability to arching over or packing of thefuel before reachingtheconveying means. 7

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a vertical longitudinal central section through a locomotive tender, illustratinganapplication of my invention; Fig. 2, a verti cal transverse section through the same, on the line a a of Fig. 1; Fig. 3, a similar partial section, illustrating a structural modification; and, Fig. 4, a side view, in elevation,

of the fuel receptacle, detached.

M invention is herein exemplified as ap-. plied in a tender, the frame, 1, of which is of the ordinary construction, and which is supported on two swiveling trucks, 2, and having a tank, 3, the front wall, 3, of which is forwardly. and downwardly inclined to a water bottom, 3" The tank also has forwardly extending lateral extensions, 3, which are inwardly and downwardly inclined on their inner sides, soas to be of sub stantially triangular section. There is thus provided, at the front of the tank, a longitudinalrecess, the rear and side boundaries of whichare downwardly and inwardly in-' clined, and which is open at its top and front. -While my invention is desirably applicable in connection with a tank of this form,'it .is not limited thereto, and the fuel receptacle, hereinafter described, may be located in a recess formed in a water tank of circular or of D section, if desired.

The forward recess. above described, of

' tion of a crane.

the tank, isoccupied by a fuel receptacle, 4, of stout plate or sheet metal, which, in the instance shown, is fitted removably in the space above the water, bottom, 3", the rear and lower side walls of'the receptacle being inclined in directions parallel with the front wall of the water tank and with the inner walls of the forward lateralextensions thereof,'respectively, and the bottom being flat, in

conformity with the top wall of the water bottom. All the open space at the forward endof the tank is'thus rendered available for fuel storage, and the inclination of the rear and side walls of the. fuel receptacle, together with the absence of pockets, projections, or reentrant angles enables the fuel contained. in the receptacle to be carried by gravityto the bottom thereof, without tendency to obstruction in its downward traverse. The top of the-fuel receptacle is preferably made slightly narrower than the lower portion, so-as to provide room forthe attachment .of lateral running boards, 5 above which hand rails, 6, are connected to the receptacle, facilities being thereby provided for an operator to pass from one end to the other of the tender. Plates, 7, having eyes, 7*, at their upper ends, are secured to the sides of the fuel receptacle, above the running boards, for the connection of'hooks for lifting the receptacle out of, and returning it to, its position on the tender by the opera- In order to prevent the condensation of moisture or vapor on, and the consequent sweating of, the fuel' ,receptacle, 'WhlCh would tend to interfere with the free downward flow of pulverized fuel, a lagging or coating of heat insulating material, 8, is interposed betweenthe outside of the re. ceptacle and the tank. The portion of the fuel receptacle which extends above the tank may be, as-shown, similarly cased, to

prevent possible sweating from difference of temperature between the outside atmosphere and the interior of the tank. Undercertain climatic conditions, the protection of the upper portion of the receptacle by insulating material may not be necessary.

Pulverized fuel is carried from the bottom of the fuel receptacle to a desired point of delivery on the locomotive,,by one or more conveyers,'9, three being shown in this instance, which are fitted to be rotated in longitudinal channels, 9*, located on or adjacent to the bottom of the fuel receptacle. The conveyers may be either of the screw type, as shown, or of any other suitable known form. 'Inorder to prevent the arching of fine fuel, which would prevent its free supply by gravity to the conveyers, upwardly cxtendinginclined guides, 10, are interposed between the conveyer channels, said guides 'meeting at their tops, and each extending therefrom to one side of a conveyer channel. The inclined side walls of the fuel receptacle a re similarly related to the adjacent conveyer channels. A vertical separating'plate,

11, is fixed above, and in substantially the axial plane of, each of the screw conveyers, and extends to or near the level of the tops of the guides, 10. The separating plates revent the formation of scmi circular arches above the conveyers by the packing ofvthe fuel, and so far reduce the spaces in which arching of the fuel could take place,

that tendency to packing is overcome by the weight of the fuel and the jarring of the ,the fuel to the conveyers, similarly to the separate plates before described, and the spaces between their outer sides may, if desired, be utilized to increase the Water capacity of the tank, by forming the top wall of the water bottom thereof with corresponding inclines.

I claim as my invention and desire to secure by Letters Patent:

1. In a locomotive tender, the combination of a frame, a tank supported thereon and having a longitudinal open space extending rearwardly from its front end, a fuel receptacle fitting into said space having a floor,

side walls, front and rear walls, and a lid or means adapted to move fuel to said outlet and to control said outlet.

3. The .combination with a locomotivetender frame and tank of an inclosed pulverized fuel containing receptacle provided with an outlet, and fuel discharging means for discharging the fuel through and controlling said outlet.

4. In a locomotive tender, the combination of a frame, a tank supported .thereon and having a longitudinal open space extending rearwardly from its front end, a fuel receptacle fitting removably in said recess, and a lagging of heat insulating material-inter polsleld between the fuel receptacle andthe ta Y 5. J In a locomotive tender, the combination of a frame, a tank supported thereon, a fuel receptacle fitting removably in a recess in said tank, lateral running boards fixed to said fuel receptacle, and attachments fixed to said receptacle for connection to a hoisting and lowering mechanism. j

6. In a locomotive tender, the combination of a frame, a tank supported thereon, a fuel receptacle fitting in a recess in said tank, a conveyer for transferring fuel from said receptacle to a point of delivery forward thereof, inclined longitudinal guide plates located on opposite sides of said conveyer, and a, vertical separating plate extending longitudinally above said conveyer.
